What I Said
I rated ONTO a Sell because I thought the stock was already discounting a stronger earnings path than the latest quarter and the peer setup justified. My original concern was not that the business lacked quality — I explicitly noted the moat, balance sheet, and gross margins — but that customer concentration, tariff exposure, and export controls were slowing the conversion of that quality into operating profit. I also pointed to a stretched 54.2x EV/EBITDA multiple and a 1.2% FCF yield as leaving little room for execution mistakes.

| LRCX | -8.0% |

Why It’s Working (Or Not)
So far, that bearish call has worked: if I had shorted ONTO at my entry price, I would be up 8.4% on the signal. The stock has fallen while the peer group has also been mostly lower, which tells me the whole semi-cap equipment complex has been under pressure, but ONTO has still moved in the direction that supported my Sell. The part of my thesis that has held up best is the valuation argument — a rich multiple and thin FCF yield were only defensible if the earnings rebound accelerated, and I have not seen evidence in this window that it has. I cannot claim the customer-concentration and export-control risks were the sole driver of the move, but the market has not rewarded the stock for the quality I acknowledged.
What Could Still Prove Me Wrong
I would be wrong if ONTO starts delivering the specific operating improvement I said was needed: revenue growth above 15% for two straight quarters and operating margin moving into the high teens. I would also have to reconsider if quarterly earnings growth turns clearly positive while the stock re-rates on durable fundamentals rather than a temporary bounce. If those conditions do not show up and the business instead slips back below 8% growth or keeps missing on earnings, my Sell remains intact.
